INSTALLATION - MIX METHOD (WITH LSG SERIES LOAD SUPPORT GRID)

STEP 1: Excavate the job site. Properly grade subgrade to allow water to flow away from any structures.  Add drainage if necessary.  Install moisture barrier if project meets a foundation with a basement.  

STEP 2: Layout geotextile fabric. This creates a barrier to prevent sediments from migrating up into the system and causing future settlement. Geotextile fabric must separate aggregates from subgrade and soils on all sides of the project. TIP:
We Recommend DuPont Geotextiles

STEP 3: Install Cell-Tek LSG SERIES Load Support Grid. This reinforces the base material to prevent lateral movement.

STEP 4: The cells should be infilled with a washed aggregate infill equivalent to a #57 (3/4”) stone to allow for maximum permeability. The cell should be filled with about one inch overtop of the grid.  

STEP 5: Spread, level and tamp.

STEP 6: Install plastic or aluminum edging. This creates a clean edge to define the shape of the surface's final contours.
 




STEP 7: Wash decorative stones and allow to dry (or use triple-washed Gravel-Lok Pebbles). The cleaner the stone, the stronger the bond. Mix stones with Gravel-Lok in a cement mixer or wheelbarrow.

MIXING RATIO:
In most cases, mixing 20-24 oz. of liquid with a 5 gallon bucket of stones is ideal. Important: a plastic 5 gallon bucket is considered ‘full’ when the contents are filled 2” below the top of the bucket. Do not completely fill the bucket to the top with stones.


NOTE: For driving surfaces please contact Cell-Tek Geosynthetics at 888-851-0051 for design advice.


STEP 8: Pour out in one small area.  

STEP 9: Level and trowel to finish.  

STEP10: Allow 24 hours to cure. Rope off treated area to protect it from people and animals. Do not walk on the surface before it has cured. Do not cover with plastic.  This will trap in moisture and cause premature curing.  

STEP 11: Apply Roller Coat using a small nap (1/2” size) standard paint roller. COVERAGE RATE:
400-500 square feet per 5 gallon container.
